Coating composition for sub-marine steel structure.

摘要

The invnetion relates to a coating composition for submarinesteel structures comprising (A) a liquid epoxy resin, (B) a hardening agent selected from polyamine, polyamide or polymercaptan ,and (C) solid proton donator particles having an average diameter of 10 mu or less, the equivalent ratio of epoxy group in (A) to active hydrogen atom in (B) being 1:0.5 to 1:2.0 and the content (C) being 1 to 25% by weight of the total weight of the composition. The present coating composition is excellent in coating workability and adhesion to steel in sea water.
